My friend and I both bought Zoom H1 portable recorders. They connect to a pc using a USB mini-b cable supplied with the recorder. My friend lost his cable but a new purchased generic one doesn't work. I've tried a generic cable with mine and that doesn't work either. Both recorders work with my original cable. What's going on? Is the USB supplied with the Zoom different in some way to a generic one or are there more than one type of USB mini?
